Flowthrough Architecture
The LTC
1350 is a 3-driver/5-receiver EIA/TIA-562
transceiver with very low supply current. In the no load
condition, the supply current is only 300A. The charge
pump only requires four 0.1F capacitors.
In Shutdown mode, two receivers are kept alive and the
supply current is only 35A. All RS232 outputs assume
a high impedance state in Shutdown or with the power
off.
The LTC1350 is fully compliant with all data rate and
overvoltage EIA/TIA-562 specifications. The transceiver
can operate up to 120kbaud with a 1000pF and 3k load.
Both driver outputs and receiver inputs can be forced to
±25V without damage and can survive multiple ±10kV
ESD strikes.
